AIT for me. We policed rocks from the lawn. Every day there were more rocks. I'll bet they're still policing rocks from the same lawns.
You got the rocks, we got the cigarette butts.
Like your rocks, the butts we had to police up were always in areas where NO ONE could smoke and would get punished if caught there. So no one did. But there were the butts anyway.
And the idiot DIs thought we were idiots. /sarc
